Welcome to the Stackhero documentation

Stackhero provides a ready-to-use Docker cloud CaaS (Containers as a Service) platform, designed for fast and reliable container deployments:

• Deploy to production with a single docker-compose up. There is no extra setup: just start your containers.
• Pick your own domain name, secured automatically with HTTPS (for example: https://api.your-company.com, https://www.your-company.com, or https://backoffice.your-company.com).
• Benefit from strong performance and robust security on private, dedicated infrastructure.
• Apply updates with one click for simple, low-effort maintenance.

You can have your containers live in production in about five minutes. Stackhero manages the infrastructure, updates, and security for you, so you can focus on delivering your applications. Read more about Docker CaaS cloud hosting.

If you wish to specify a different Node.js version, follow these steps:

1. Open the file docker/my-app.dockerfile, which defines the Docker image for your app.
2. Locate the first line that reads FROM node:<version>-alpine.
3. Replace <version> with your chosen Node.js version. It is recommended to use the Long-Term Support (LTS) version. You can check the latest LTS version on the Node.js website. For example, to use the latest LTS version (currently 22), update the line to FROM node:22-alpine. If you prefer a specific version number, you can use something like FROM node:22.13.0-alpine.
4. Save your changes to the Dockerfile.
